Our Verdict

Logitech G815 LIGHTSYNC RGB

Logitech G915 X

The Logitech G815 LIGHTSYNC RGB and the Logitech G915 X are fairly similar low-profile mechanical gaming keyboards. Both models have wired-only connectivity and offer similarly excellent raw performance. The only differences are fairly minor build quality differences. The G915 X is newer and has higher-quality PBT keycaps that aren't prone to developing a shiny, slippery texture after extended use. It also has a thicker top plate made of aluminum, which lends a premium look, feel, and rigidity. Just note that it also contributes to somewhat louder typing noises. Furthermore, while you can only program macros to a set of five dedicated macro keys on the G815, you can program macros to any key, including the dedicated macro keys on the G915 X.
